BOTTLE STOPPER.

Application filed September 8, 1922.

To all whom it may concern Be it known that I, SAMUEL M. SGHEN- item, acitizen of the United States, and a resident of Lyndhurst, BergenCounty, New Jersey, have invented certain new and useful Improvements inBottle Stoppers; and I do hereby declare the following to be a full,clear, and exact description ofthe invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to bottle stoppers and more particularly to taperedand ground in glass stoppers and the lip or lips of the containers towhich they are held and which guide and govern their movement, and itsobject is to provide a simple and effective non-sticking glass stopper,that may or may not be of the sprinkler or dropper type, there being ametal cap connected with and non-removable from the stopper, andengaging under the lip of the bottle neck; and by which the stopper iseasily turned and removed. There is a spring included between the capand stopper to hold the stopper seated.

Other details of the invention will be hereinafter described andclaimed. I

Referring to the drawings, in which like parts are similarly designated-Figure 1 is an elevation of the cap and stopper on the bottle;

Fig. 2 is a vertical, central section,

Fig. 3 is a transversesection on line 3-3,

Fig. at. is an elevation of the bottle neck for the construction shownin Figs. 13;

Fig. 5 is a view partly in section, showing a modification,

Fig. 6 is a section on line 66 of Fig. 5;

Fig. 7 ,is a vertical section showing a modification of the cap; I

Fig. 8 is a section 011 the line 88 of Fig. 7;

Fig. 9 is an elevation of the bottle neck.

Tapered and ground in glass stoppered bottles heretofore made have theinside of the neck of the bottle and the outside of the stopper groundto fit. The taper of these interfitting parts is slight, in order thatthey may hold one to the other. By reason Serial No. 586,915.

of this slight taper they often stick tight, causing the bottles to bedifiicultto open.

According to my invention this taperis made greater than usual, in fact,sufliciently great to prevent, sticking, and reliance is placed on aspring to holdthe stopper in the bottle neck. A i p By this means I haveovercome a very great objection to tapered and ground in glass stopperedbottles.

Referring to the form shown in Figures 1-4:; 10 represents the bottlewhose neckis provided with a lipll having a plurality ofgrooves12therethrough, usually three, and the lower edge of the lip 11is provided with two lug-engaging faces 13 and 14; at differentelevations and a vertical limiting face 15.

The neck of the bottle is also provided with a mouth 16 of wide taperand the stopper is correspondingly tapered, and both are ground, asusual. This'taper or conicity is greater than that which is usual, andis such that the stopper will not stick tightly in the bottle mouth.

The stopper 1'? is provided with the customary grinding groove 18 whereit joins the stopperhead 19. This head is provided with a plurality oflongitudinal grooves 20, preferably three, and with aguide extension 21of reduced diameter, at its top, while the bottom of the stopper may ormay not be provided with a glass rod extension intended to dip into thecontents of the bottle.

The stopper may be provided with a sprinkler or dropping bore 22, thathas a lateral extension 23 adapted to register with a groove 24 in thebottle neck when the stopper is turned into properposition.

A metal cap 25, is provided with one or more depressions or crimps 26that ,actjas lugs for engaging the grooves 20 in the stopper head, andby which the stopper'is turned. There are also provided on the loweredge of the cap one or more crimps that form a lug or lugs 27. Theselugs may ride through the slots 12 to permit the removal and theinsertion of the stopper. They may. rest on the surfaces 13 to hold thestopper so that the bore 2223 registers with the: bottle groove 24:, orthey may rest on the surfaces 14 with their sides against the stopsurface to hold the stopper in place and the bore and groove out ofregister.

The cap has a hole that co-operates with the stopper extension ofreduced diameter 21, and in this form the extension 21 projects throughthe top of the cap 25.

Surrounding the extension 21 and between the head 19 and cap 25 I placea coil spring 122, the object of which is to hold the stoppe seated inany rotated position of the cap when the cap lugs 27 engage under thelip of the bottle neck, and to hold the stopper against ---unduelongitudinal movementin the cap cap may be provided with a thimble extenwhen removed from the bottle. To this end the grooves 20, in the stopperhead must be closed. attheir top but may be open at the bottom as shownin Fig. 5 at 20, and the sion 125 surrounding the glass extension 21 toprotect it against breakage, and if desired one of the surfaces 14 or13, may be omitted. from the bottle neck, i. e. united into one surfaceas at 113 Figures 6 and 7.

The construction Fig. 5 is preferably such that the distance a betweenthe top of extension 21 and the extension protector .125 is equal to theheight between the surfaces. 13

. and 14, andthe lugs 127 are peripherally end of extension 21.

127, which are simply tongue extensions of the metal cap turned at rightangles inwardly of the cap.

. The thimble extension of the cap may also be directed inward at itsend as at 120 Fig. 7

It is, of course, obvious that if it is desired to prevent the stopperfrom being removed in an of the forms shown it is sim 31 1 necessary toomit the groove 12 through the bottle lip and crimp the cap underthebottle lip. 'lhe cap may then be turned to position the stopper todischarge through the bore 2223, but the stopper cannot be removed fromthe bottle. I I

1 While I have shown, by preference, three grooves 12 through thebottle; lip, three grooves 20in the stopper head and three lugs, 27 or127, I wish to be understood that I do not limit my construction to anyparticular number.

. Ihave also shownthree grooves 24 in the stopper seat, and thesepreferably correspond to the number of. lugs 2.7 or 127 on the cap, sothat no attention need be paid. when inserting the stopper in thebottle, to insure the proper position of the stopper bore 2223. Only onesuch groove 241 is operative in a definite position of the cap onthebottle, and only one is absolutely necessary; the others, however, areconvenient.

I claim- 1. A bottle stopper, a cap connected thereto and movablelongitudinally thereof, and a spring between the stopper and cap; incombination with a bottle having a lip said cap having lugs engagingbelow said lip and permitting the cap to rotate.

2. A bottle stopper, a cap connected and freely movable with respectthereto, and a spring between said stopper and cap urging the stopperlongitudinally of the cap, said cap having means for attaching it to abottle neck, the end of the stopper being concentrically spaced from theskirt of the cap.

3. A bottle and a glass stopper therefor, in combination with a cappermanently securedto said stopper and detachably secured to saidbottle, said cap having rotary movement with respect to the bottle and1on gitudinal movement with respect to the stopper.

4. A bottle having a lip provided with a plurality of surfaces ofdifferent elevation, in combination with a glass stopper, a capconnected thereto, lugs on said cap arranged to engage said surfaces anda spring between the cap and stopper. 7

5. The combination with a bottle having a vertically grooved lip; of aglass stopper for the bottle, a cap in crimped connection with saidstopper, lugs on said cap for passing through the grooves in the lip anda spring between the cap and stopper.

6. The combination with a bottle having a lip and having one or moregrooves in its stopper seating face communicating with the interior ofthe bottle; of a glass stopper hav ing a bore capable of registeringwith said groove, a cap connected to said stopper and having an openingin its top cooperating with the top of the stopper and a spring betweenthe cap and stopper.

7. The combination with a bottle having a lip and a groove in thestopper seating face communicating with the interior of the bottle; of aglass stopper having a bore arranged to be brought into register withsaid groove and also having a reduced extension at its top, a cap incrimped connection with the stopper, said cap capable ofslightlongitudinal movement on the stopper and having a holeco-operating with said extension, a spring between the cap and stoppersurrounding the extension, and lugs on the bottom of the cap engagingunder said lip.

8. The combination with a bottle having a lip provided with verticalgrooves therethrough and having on its imder face a set of lug engagingfaces between adjacent grooves, said bottle also having a pluralityguided, and a spring of grooves in its stopper seat; of a ground glassstopper having a bore capable of registering with a groove in its seat,a reduced extension at the top of the stopper and a rod extension at itsbottom, said stopper having a plurality of grooves in its head, a caphaving crimps engaging the grooves in the stopper head and lugs at thebottom engaging said :Eaces, said cap having a thimble extension inwhich said stopper extension is between the cap and stopper surroundingthe stopper extension.

9. A bottle stopper, a bottle, a bottle engaging cap inovably connectedto the stopper and a spring between the cap and stopper to urge thestopper to its seat in the bottle.

10. A bottle stopper, a bottle, a bottle engaging cap connected to thestopper and longitudinally movable with respect thereto, and springmeans between the stopper and cap to urge the stopper to its seat in thebottle independently of the movement of the cap.

11. A bottle stopper, a cap connected and freely movable with respectthereto, a spring between the bottle and cap urging the stopperlongitudinally of the cap, said stopper having a taper greater than thecustomary taper for fitting a correspondingly tapered bottle neck, andmeans for attaching the cap to a bottle neck.
